10 all whom it may concern:

Be it lrnownthat 1 Joan JULIUS Srorzn, a citizen'of the United States, and I resident of Beresr'ord, in the county ofUnion and State of South Dakota, have invented a new and improved ()donieter, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved odometer, for use on engines and other motors and machines, and arranged to accurately indicate the speed of the machine, thus permitting the attendant,

in charge to regulate the speed of the machine according to the work to be performed.

The invention consists of novel features and parts and combinations of the same, whichwillbe more fully described hereinafter and then pointed out in the claims.

l A. practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar c aracters of reference indicate correspondin parts in all. the views.

Figure 1 is a ace viev; of the improvement; Fig. 2 is a transverse section of the same on the line 2-2 of Fig. 1; Fig.3 is a sectional front elevation of the same on the line 33 of Fig. 2; and Fig. at is a similar view of the same on the line 4 of Fig. 2. T

The odometer is mounted on a bracket A, attached to a support B, arranged on the engine or other motor or machine, the speed of which is to be indicated by the s eed indicator. On the bracket A is ad ustably secured a casing C, by the use of a bolt D, and in the said casing C is journaled a shaft E, carrying on its outer end a gear wheel F, in mesh with a gear wheel G, secured on the shaft H, of the engine or other motor or machine the speed of which is to be indicated. On the shaft E is secured a worm I, in mesh with a Worm wheel J, arranged within the casin C and mounted toturn of the bolt D above mentioned and shown in Fig. 2. The worm wheel J is provided at its front with a cen tral stud J, on which is secured a pointer K, arranged in front of a plate L, havin a through which appears one of two sets of numerals N", N arranged on a dial N, mounted to turn loosely in the casing (I on a bushing O, held loosely on the stud J, and which bushing also carries the plate L. The dial N is vided at the to with a handle N, extefad 'ing through a slotin the top of the casing C to the outside thereof, to permit the operator to turn the dial N, so as to bring either set ofnuinerals b or N in register with the row of apertures L in the plate L. By thearrangement described, the odometer can be applied to a shaft H, driven in either direction, as the operator will then set the dial N correspondingly, that is, to bring the corresponding set of numerals N or N in register with the apertures L. The worm wheel 3 is provided with a hundred teeth and the dial N is divided in a hundred arts, and the gear wheels F and G are ali e in diameter.

N w when the odometer is in use and the shaft H is running, then the gear wheels G andl rotate the Worm shaft E, which by the Worm 1' causes the worm wheel J to rotate slowl; and with itthe pointer K, so that the latter indicates on the set of numerals N or N appearing through the apertures L or the plate L.

As shown in Fig. 1, the pointer K travels in the direction of the arrow a, hut in case the shaft H runs in a reverse direct-ion, the dial N is shifted to bring the set of numerals N in register with the apertures L, the pointer K then traveling in the reverse direction of the arrow a.

It is understood that the dial N is graduated in tenths from zero to hundred in both directions and the Worm wheel J is provided with-one hundred teeth, and at every revolution of the worm wheel I, the dial N is turned the distance of one hundredths part of its raduation, and at every ten revolutions of the worm wheel I, a graduation mark N (or N will appear in the corresponding aperture L. Now by the op erator timing the pointer K as it makes one complete revolution at a'given or normal rate of the speed of the shaft H, it will be easy to determine thesubsequent speed of the shaft H, if the latter runs faster or slower by again timin the pointer as it and vances from between tlie adjacent ten points.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: i

1. An odometer comprising a casing, a belt for securing the casing to a support, the bolt projecting into the casing, a worm wheei mounted on the bolt within the casing and having stud projecting from its front face, a plate secured upon the stud pro Filled with a circular 170W of apertures, a pointer 0n the stud in front of the plate, (linl loosely n'iounted 011 the stud between the plate and '\\01'1;1fivheel, and a shaft mounted in the casing and provided with a Worm meehmg with the WOlln wheel.

An oilenietei comprising a slotted casing adapted to be secured t9 3 suppmfit, a mum wheel mounted. in the biasing and pro- Yialecl with a stud projecti frem it fee a bushing mounted on. the stud, plate carried by the bushing and having 21 Gil"- culur yew of epertuies, a dial leesely mounted on the bushing between the worm Wheel and plate and having two sets of numerals re-0n, said dial being provided with a .lle projecting through the slot. of the casing, pointer secured to the stud of the WOl-Cill wheel in front of the plate and a driven shaft mounted in the casing and pro- 20 JOEE JULEUS STONE.
